I`m unable to decode stream from my local 10-bit h265 DVB-T2 record. It is detected as 0x0 dimensions, etc. Shoud it be decoded?

The stream does not contain IDR pictures and instead is using I slices in a TRAIL picture for a starting point. However, I rely on IDR pictures to get the place to start decoding. Fortunately, the stream has AUD_NUT NALUs that can be used as starting points.
I tried treating AUD_NUT as IDR for use as a place to start decoding and your stream did decode in DGIndexNV without artifacts, confirming the use of TRAIL pictures with I slices. There are more places where I have to treat AUD_NUT as IDR, e.g., GOP stepping, indexing and DGI file, demuxing, etc. Also need to modify DGDecodeNV in the same way. Finally, it all needs to be done for both AVC and HEVC video. I will implement this but it will take some time.
